XPS 15-9570, Audio crackling and popping

I have an issue that renders the audio on this laptop unusable.

I have a new XPS 9570, and occasionally (I stress that word because 75% of the time there is no issue) when playing audio, either through the built in speakers or through the audio jack, there is a loud popping and crackling noise that accompanies the audio. This renders any audio generated by the laptop unusable.

Because the issue is not always present, it is very hard to debug since you can't know if the issue was actually fixed, or just temporarily gone.

Testing I have done thus far:

When playing a continuous tone, such as generated by<TOU> , the issue is still present.

The crackling and popping increases with system volume, so if I turn the volume up on the laptop, the crackling becomes louder.

I have reflashed the BIOS to the newest version, uninstalled realtek, reinstalled realtek, disabled wave-maxx-audio (or whatever it is called), and tried using the built in windows drivers. Nothing has worked.

And note that when playing from bluetooth, there is no issue. So it is not a software issue in that way.

Very disappointing that on such an amazing laptop (it truly is amazing), an integral part of it is basically useless.

After 5 days of hopeless troubleshooting (severe crackling coming both from the laptop speakers as well as headphones was driving me crazy) and several calls with Dell support (the best they could offer was motherboard replacement), what finally solved the problem for me was reducing the DPC latency.

Specifically, based on recommendations from the community

1/ I installed free DPC Latency Checker, which showed my DPC latency being constantly at around 16000us with acceptable levels being below 2000us

2/ I tweaked the Power & Sleep inside Win10 - various changes offered various levels of improvement, with the simplest advice being 'select any power plan other than the Balanced one'  and ‘remove sleep / power saving options’. That substantially helped to get rid of the crackling, but the latency was still at around 2000-4000us

3/ after installation of the Dell Power Manager utility and selecting 'Ultra Performance' Thermal management, the latency finally reduced down to just 1000us, while - ironically - the notebook became significantly quieter than before

Same for me, had this problem since I've got the laptop, tried all possible suggestions without any result. Tuning settings in WaveMaxx help to reduce cracking slightly but I still hear it. Customer support wasn't helpful either.

The only reliable sort of solution for me was going to apple store and buying usb-c jack, with it sound works flawlessly. Shame on you, Dell.


I purchased a refurbished (by Dell) XPS 15 9570 last year with the intention of using it only for music production. It has been nearly a year of struggling with crackling and hissing audio issues. I have tried the recommended fixes on the Dell forum, but absolutely nothing has worked. It is so bad I no longer am inspired to make music at this time. I am quite upset that nothing has been done and no updates have been pushed to users. To be honest, it's been a waste of a lot of time and money. Anything you can do would be appreciated.


Well done @tblockey  for the fix. Go to MaxxAudioPro app and turn bass to 12. done.



Try these settings in maxx audio. leave boost on but tone it down to a quarter and up the details to half


I've spend 10-15 hours on this issue now. Mainboard changed twice and what not. I've been able to remove the crackle by uninstalling MaxxAudio on a previous BIOS, but this made another DSP function go crazy (autonomously behind the scenes), where it adjusts the volume up and down, depending on the music loudness. This completely removes all dynamics and distorts the signals now and then (this might be harder to notice for the "average Joe", but very clear if you work with music or similar).

I've said all the time that this is a software problem, but Dell is apparently not able to explain or make Realtek find and fix the problem.

The only thing that works 100% correctly, is to install Windows cleanly (from Microsoft media), and use the old (before 2019) High Definition Audio driver (which is provided and made by Microsoft).

This way there's no Realtek and MaxxAudio **bleep** on the drive, and the audio is fixed and sound is crisp and clear.

Only problem is that Microsoft have included a new High Definition Audio driver in 2019, and Windows 10 will sooner or later force an update to this version - which unfortunately doesn't work either (also MaxxAudio infected).

I thought I'd bought the best laptop on the market, and it probably is, if it wasn't taken down by crappy Realtek software. With all the users complaining, it is incredible that Dell is not doing more to fix it. They could start their own analysis by installing a clean Windows from Microsoft, and go from there (see when and what <Substitute character removed> the system for every single update they apply).

I could of course do it myself, but I've sort of hoped that Dell would do this 4 months ago with all their engineering power.

Anyway, I will have time in October to do an in depth analysis, and I'm sure I will find the exact cause (which I'm going to share on youtube or similar). But why are big companies like Dell becomming sitting ducks when it comes to fixing simple stuff like this?

How many people have not spend hours on this? - Dell only needed to take the old Microsoft driver, re-package it, and ship it to all of us - and make it pretend it was the latest and greatest. This way we would at least have working audio, and I think we can all live without the "genuine" Realtek/MaxxAudio crapware that just waste everyone's time...

In 1995 I was as disappointed as I am now by an expensive Pioneer video grabber solution, and I haven't bought anything from them since then.


I had the problem that my XPS 15 had too much bass. Now I don't have this problem anymore - how I fixed it:

  • I uninstalled Realtek Audio Drivers in System Settings ("Apps") and rechecked in Device-Manager
  • Uninstall Maxx Audio in System Settings ("Apps")
  • Now the sound icon should be red -> no sound
  • Reboot
  • Windows fixed it itself, sound is here again and without too much bass.

I don't understand Dell why the install this Maxx Audio **bleep** which sounds very bad.


@damaartenman  I had given up on reading any of this thread but after posting my own comment I read yours and it's fixed my problem entirely thank you! 


Hi Alan, 

I've been following this thread for a long time, I bought this laptop back around Christmas. My audio then would be fine for a while then suddenly start buzzing and crackling but it would go away, now I have a persistent low base sound roar and distortion and it's gotten to the point that I cannot hear what's being said. 

I assume I have the same issue that this page relates to. Sorry to be lazy but I don't want to read through 42 pages of responses, can you help me. 


finaly problem solved Who ever found this, thumbs up. Disable Maxx audio worked for me
